Lithuanian designers Inesa Malafej and Arunas Sukarevicius have created this Dancepants Kinetic Music Player concept. It allows you to use the kinetic energy to generate the power for the MP3 player, through running and dancing. The kinetic module is attached to the pants legs with the connection running along the leg up to a pocket where the MP3 player is connected. Want to listen longer? Just dance. One more picture after the jump.
